"Community": School is Back in Session

Queer cartooning has a storied history at Comic-Con and this gathering will celebrate the launch of a new anthology celebrating 40 years of LGBT stories, characters and creators. "No Straight Lines" showcases lesbian underground comics to trans web comics and almost everything in between. Moderator (and anthology editor) Justin Hall chats with an all-star panel including Paige Braddock, Alison Bechdel, Ed Luce and Eric Shanower.

Presented by SyFy, the 24th annual Eisner Awards honors comic creators and work published in 2011across 28 categories. Special guest presenters - this year's roster includes George R.R.
